Help Needed Please. Throttle

[Toyota1986]

some background info - Put foot down on pedal and car wont rev past 2000rmp. plugged in the computer and the following errors come up -

P0121

P0123

replaced the sensor on the pedal and no luck still does the same thing. Now garage is saying it could be the throttle body itself, tried cleaning it etc nothing.

so been looking around, need some advice. The numbers on my throttle body are as follows

22030-0D020

4G29

00924

I've seen a few online on eBay but the numbers dont all match but does that matter? as when i ring around car breakers yards they don't ask for them just the make and model etc

please have a look at this throttle body, will this fit? item number if link doesn't work is 350806275090

My car is a Corolla 1.6 petrol, 54 reg

any help would be much appreciated. Thank you.
